164 TRINIDAD AND TOBAGO BULLETIN. [XX. 2, 3 & 4. 



61. Calliphlox amet'.ystina. Gmel. Amethyst. 

 Calothorax enicuous. Leotaud No. 73. 



This is one ol^ the smallest and one of the rarest of the Trmidad 

 humming birds. 



Neck bronze green above. Tail brown edged with cinnamon 

 inside. Throat brilliant amethyst followed by dull white. 



Abdomen rusty brown. The total length only about 80 mm. 



The female differs from the male in having the throat white, 

 sides of neck brown and abdomen pale chestnut. 



This humming bird is recorded as rare by Leotaud and was not 

 seen by either Chapman or Hellmayr. I saw a single specimen 

 feeding at the flowers of Leonotis neptaefolice al WiUiamsville on 

 June 17, 1918. I have no further record of its habits or nesting. 



62. Chrysolampis mosquitus, Linn. Ruby Topaz. 



-Mellisuga moschita. Leotaud No. 74. 



This brilliantly coloured species is apparently not uncommon. 

 The male has the crown of the head and hind neck metallic red. Chin, 

 throat and chest bright metallic golden orange. Sides of neck, back, 

 rump, upper wing coverts and upper tail coverts chestnut. Tail 

 chestnut with dark edges. Upper parts of body greyish-brown. 

 White tips on thighs. Upper tail coverts cinnamon. Bill dull black, 

 short and comparatively short. 



The female is bronze green above and dusky grey beneath the 

 throat with a median darker stripe slightly metallic. Centre tail 

 feathers bronze green. Others chestnut at base, then darker and 

 tipped with a triangular spot of white. 



The species frequents the flowers of Immortelle in the dry- 

 season and I shot one (a female) at these flowers in Maracas Valley 

 on January 28, 1921 . 



I have not seen the nest but Schomburgk {Reis. Guian. Ill 705) 

 describes a nest found in British Guiana as being in the fork of an 

 isolated Melphigia bush. The inside of the nest was lined with 

 vegetable down and the outside was covered with lichen. 



63. Chlorestes coerulens, Vieil. Saphir. 

 Hylocharis coerulens. Leotaud No. 77. 



According to Chapman this is the commonest of the tree 

 haunting hummers, but I have never been able to identify it for certain 

 without shooting specimens. 



The male is dark green above and bright glittering green below. 

 Wing feathers brown. Tail steel blue. Under tail coverts green. 



The female is whitish on the under surface with green tips 

 to feathers. 



I have no records of nest or habits.
